How to correctly use MONTHS function?

I am trying to find the difference between dates in "months". I have refferred to the following documentation on usage of "months" function and I even tried out the example given in the documentation but all I get is an error.

https://in.mathworks.com/help/finance/months.html

Code: MyMonths = months('may 31 2000', 'jun 30 2000', 1)

Error: Check for missing argument or incorrect argument data type in call to function 'months'.

What am I missing?

Type

which  months 

at the command window

If you see more than two functions with filenames months then it may be due to custom function and not standard matlab function

You should use datetimes, durations and the between function for this:

>> d1 = datetime('may 31 2000', 'InputFormat', 'MMM dd yyyy')
d1 = 
  datetime
   31-May-2000
>> d2 = datetime('jun 30 2000', 'InputFormat', 'MMM dd yyyy')
d2 = 
  datetime
   30-Jun-2000
>> monthsbetween = between(d1, d2, 'months')
monthsbetween = 
  calendarDuration
   1mo
